Description
The BARTEC Varnost enclosures, type 07-56.1-…./…. and
type 07-55.1-…./…., are available as enclosures with lid or as
cabinets with door. The enclosures serve for the admission of
certified components in combustible ranges. They are used for
connection with lights, devices and sensors.
The walls of the enclosure, lid/door and base consist of several
edged and welded high-grade stainless steel of at least 1 mm
(0.04 in) thickness.
The flange plates with tapped holes for the cable and conduit
entries are at least 3 mm (0.12 in) thick.
The IP protection class is realized by a seal in the lid or in the
door.
The enclosures are mounted with mounting brackets found
outside of the enclosure wall.
The enclosures are also suitable for intrinsically safe electric
circuit connection. For this application, special marking is
required.
The enclosures can be used in hazardous areas of both zone 1
and 2 with certified explosion subgroups II and the temperature
class T5/T6 and as well as in zone 21 and 22. Enclosures and
cabinets with windows shall only be used in conditions with low
level mechanical risk.
Safety instructions
The supplied Ex empty enclosures are U-certified components
which serve as a basis for completely certified devices which
then in their entirety must still be tested and approved by a
specified agency for capability for use in potentially explosive
areas.
The enclosure may be operated only if it is clean and not
damaged in any way. Dust deposits > 5 mm (> 0.2 in) must be
removed.
Utilization in areas other than those specified or the modifica-
tion of the product by anyone other than the manufacturer is
not permitted and will exempt BARTEC Varnost from liability for
defects and any further liability.

Transport, storage
CAUTION
Risk of injury due to heavy loads.
• Use an appropriate carrying aid or an appropriate means
of transport (e.g. a fork-lift) with an adequate load-carrying
ability.
• Ensure that the lifted load will not tip over or slip off.
NOTICE
Damage through incorrect transport or incorrect storage.
• Transport the distribution box in original packaging, handle
with care, and do not drop.
• Store the distribution box dry in original packaging.
Assembly, installation, and
commissioning
WARNING
Risk of serious injury due to incorrect proceedings.
• Only qualified personnel who are authorized and trained to
assemble electrical components in hazardous (potentially
explosive) areas may do any of the assembly, disassembly,
installation and commissioning work.
• For assembly and operation of explosion protected
electrical equipment, relevant installation and operating
regulations are to adhere (e.g. Betr.SichV, IEC/EN 60079-14
and series DIN VDE 0100).
• The data on the label and the EEC design test data are to be
observed. Further technical information is provided in the
BARTEC catalog and on the product itself.
• Do not open the distribution box when energized.
• Follow the components mounting instructions/operating
instructions.
Assembly / disassembly
DANGER
Death or serious injury because of a missing protective
earth connection.
• Metallic conductor entries must be connected to the
ground. With plastic enclosures, BARTEC Earth loc or
appropriate ground plates serve the similar purpose.
• Protective earth connections have to be protected against
self-loosening.
• By assembling/disassembling of cable glands and/or plugs
with counter nuts tighten always counter nuts and NOT
plugs or cable glands - otherwise the seal may be damaged.
NOTICE
Damage to elements due to incorrect installation
dimensions.
• The minimum spacing between the mounting holes must be
observed, see manufacturer`s instructions.
When processing the enclosures, attention must be paid to
ensuring that there is suitable minimum spacing between
individual boreholes and from the sealing edge of the enclosure
so that enclosure with the fittings will be able to withstand an
impact test.

Operational Instruction (Original) / EN4Empty enclosure Type 07-56.1-…./…. Type 07-55.1-..../.... 5
The minimum spacing depends on the geometrical dimensions
of the built-in components, a longer lever will require an
increase in the minimum spacing and accordingly must be
determined specially.
For accommodating use only components certified for the Ex
areas such as terminals, switches, cable glands measuring
instruments, control equipment and display units.
Check when assembling:
– Use suitable tools.
– Pay attention to the type of mounting required (for fitting into
enclosure/attachment with junction box).
– For enclosures placed in outdoors, steps must be taken to
ensure smooth operation, for example rain protected roofs,
and if necessary, sufficient enclosure protection.
NOTE Metallic enclosures for intrinsically safe facilities do
not have to be attached to an equipotential bonding system,
except if it is required by equipment documentation.
Installation
WARNING
Risk of injury due to incorrect proceedings.
• Extensions or modifications to the distribution box are only
permissible if the manufacturer’s approval is obtained first.
• The IEC/EN60079-14 must be observed.
Check when installing:
Installations for the highly combustible range must exhibit
an EEC design inspection certificate. Installation of these
components must take place in such way, so that at least the
enclosure remains IP54.
Connection of cables and conductors to equipment in hazardous
areas require Ex certified entries, which are suitable for
respective cable and conductor types.They must possess the
protection type “e” and contain a suitable sealing gasket, so that
protection class of the enclosure remains at least IP54.
Take care when connecting conductors:
– Always use suitable crimping tools when crimping the wire-
end ferrules to ensure a consistent quality of pressing each
time.
CAUTION Take care not to damage the individual wires.
– Tighten all terminal points securely (including those not in
use).
Commissioning

of the work relating to maintenance and fault clearance.
• EC/EN 60079-17 must be observed.
• Do not open the enclosure when energized.
Maintenance
WARNING
Risk of serious injury due to electrostatic charging.
• For windows with surface resistance of >109Ω, potential
electrostatic charging hazard exist. Only wet cleaning is
allowed.
The operator of the enclosure must keep it in good condition,
monitor it and clean it regularly. He has to determine the
maintenance intervals depending on the conditions of use.
Within the scope of maintenance:
– Check the enclosure, actuating elements, cable entries,
sealings, and cables regularly for cracks and damage.
– Make sure that they are properly established.
Fault clearance
The device is defective if the encapsulation is damaged and/or if
one of the components does not function any longer.
In this case:
– Replace defective parts in the encapsulation with original
parts immediately.
